VMWare HP Microserver Gen 8

Had very slow disk performance on a RAID 1 array in ESXi on my new HP Gen 8 microserver and found hardware acceleration was disabled.

The answer appears to be rolling back the storage driver as per http://homeservershow.com/forums/index.php?/topic/9141-low-io-performance-with-esxi-60/page-3

esxcli software vib remove -n Hewlett-Packard:scsi-hpvsa
esxcli software vib install –viburl=/vmfs/volumes/DATASTORE/scsi-hpvsa-5.5.0-88OEM.550.0.0.1331820.x86_64.vib

Driver available from http://vibsdepot.hp.com/hpq/mar.30.2015/esxi-550-drv-vibs/hpvsa/

note:

First update all drivers via

PXELinux Windows PE

The following batch file describes the creation of a Win7 PE boot environment and generates an ISO that is then bootable. For our needs we use PXELinux so note the echo in the batch file” echo Preparing peimagexfiles” below.
